System and method for processing mircotransactions

ABSTRACT

The method and system of the invention provide a variety of techniques for processing a microtransaction, wherein the microtransaction is a low monetary amount. In accordance with the invention, the method starts with a customer initiating a purchase through interaction with a merchant. The purchase is associated with purchase information, which includes the particulars of the purchase, such as the purchase price. In the purchase, the customer uses a transaction account, obtained from a payment enabler. The merchant submits the purchase information for processing of the purchase information. Thereafter, the purchase is classified as a microtransaction, if the purchase price is below a predetermined monetary amount. Thereafter, the purchase information is forwarded for processing based on the classifying, i.e., as a result of the purchase being classified as a microtransaction. Then, upon receipt of the purchase information by an appropriate recipient, such as an interchange entity or an alternate interchange entity, the purchase information is processed to effect the microtransaction between the customer and the merchant.

The subject matter of this application is related to the subject matterof Provisional Application U.S. Ser. No. 60/348,139 filed Jan. 15, 2002,assigned or under obligation of assignment to the same entity as thisapplication, from which application priority is claimed for the presentapplication. Provisional Application U.S. Ser. No. 60/348,139 isincorporated herein by reference in its entirety.

FIELD OF THE INVENTION

The system and method of the invention relate generally to the field ofelectronic commerce, and more particularly to the processing oftransactions involving small monetary amounts.

BACKGROUND OF THE INVENTION

Various transaction accounts, including transaction accounts utilizingphysical credit cards, for example, are commonly used in retail,business and other transactions. A consumer may use a transactionaccount to purchase a good or service from a merchant using that type ofinstrument. When the consumer interacts with the merchant to initiatethe purchase using a credit account, for example, a sequence ofelectronic processing takes place. This processing may involve anestablished interchange entity such as Visa™ or Master Card™, forexample. The interchange entity may interact with a lending institutionor other payment enabler, such as a bank, that extends a line of creditto the customer. Each of the customer, the interchange entity, and thelending institution interact with each other pursuant to establishedterms of account that each party has agreed upon.

It should be appreciated that the interchange entity performs a varietyof processing in conjunction with handling an electronic transaction.Various administrative and other costs are associated with thisprocessing. As a result, the interchange entity typically charges an“interchange fee” as compensation for executing the transaction. Theamount of this interchange fee may vary. Typically, the interchange feeis a percentage of the purchase. Further, a minimum interchange fee isoften imposed by the interchange entity, regardless of the amount of thetransaction. Illustratively, this minimum interchange fee might be a $3charge. This minimum threshold results in problems with purchases ofsmall monetary value.

For example, a customer may purchase an item from a merchant for $4. Theselling merchant is typically responsible for paying this interchangefee to the interchange entity. If the minimum interchange fee is $3, themerchant's net receipt on selling the item is $1, i.e., $4−$3=$1. Thisreturn may not even cover the cost of the item, and certainly reduces oreliminates the possibility of a profit margin for the merchant.

Accordingly, transactions of a low monetary amount are typically notprocessed using a transaction account, such as a credit card account, towhich an interchange fee is applied. However, a significant portion ofthe transactions effectuated in the national economy are small dollarsales. It would consequently be beneficial in a wide variety ofsituations if a transaction account could be used to pay for lowmonetary amount transactions. In one regard, these low monetary amounttransactions may be characterized as “microtransactions.” As usedherein, a “microtransaction” may be or include any transaction between afirst person or entity and a second person or entity in which the costof an interchange or other processing fee might discourage suchtransactions from taking place. Other problems exist.

SUMMARY OF THE INVENTION

The invention addressing the problems above, as well as others, relatesin one regard to a system and method for processing microtransactions inconjunction with operation of an interchange entity, while stillmaintaining transaction viability for the merchant and otherparticipants.

In accordance with an embodiment of the invention, the inventive methodmay begin with a customer interacting with a merchant to initiate apurchase. Illustratively, this interaction might be performed using aclient machine connected to the Internet. The purchase is associatedwith purchase information, which includes the particulars of thepurchase, such as the purchase price, quantity, tax and other data. Inthe purchase, the customer may identify a payment enabler transactionaccount. The merchant submits the purchase information for processing ofthe purchase information. For example, the submission of the purchaseinformation might simply include the merchant entering information intoa cash register or other point of sale or other terminal.

The purchase may be classified as a microtransaction if the purchaseprice falls below a predetermined monetary amount. If so, then thepurchase information may be forwarded for differential processing basedon that classification, i.e., as a result of the purchase beingclassified as a microtransaction. Subsequently, upon receipt of thepurchase information by a recipient, such as an interchange entity, oran alternate interchange entity, the purchase information may beprocessed to effect the microtransaction between the customer and themerchant.

In accordance with one embodiment of the invention, an alternateinterchange entity is utilized in lieu of the traditional interchangeentity. This alternate interchange entity may process themicrotransaction charging a lower interchange fee.

In accordance with another embodiment of the invention, a merchantprocessing a pending transaction may, for example, interact with analternate interchange entity. The alternate interchange entity may inturn interact with a traditional interchange entity. In this embodiment,the alternate interchange entity may collect or “pool” a plurality ofmicrotransactions from one customer or a number of customers. Once thepool is formed into an aggregated transaction, the alternate interchangeentity may forward the aggregated transaction to the interchange entityfor processing as a single transaction. As a result, only onetraditional interchange fee may be recorded against one cumulativetransaction, reducing the incurred interchange expense.

In accordance with another embodiment of the invention, the merchantprocessing the pending transaction may interact directly with theinterchange entity. In this embodiment, the interchange entity utilizesdifferent protocols for a microtransaction and a non-microtransaction totrigger differentiated processing for each.

These and other aspects and advantages of the invention will be apparentfrom the detailed description which follows.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

The invention provides a method and system for viably processing amicrotransaction of a low monetary amount. As used herein, any term inthe singular may be interpreted to be in the plural, and alternatively,any term in the plural may be interpreted to be in the singular.

In accordance with one embodiment, the method of the invention may beinitiated by a customer making a purchase. It should be appreciated thatpurchase information, such as the customer's name, account number,dollar amount of the transaction, tax amount, date, time, location andother data, for example, may be associated with the purchase.Illustratively, the customer may interact with a merchant over theInternet using a computer or other client, for instance using a browserinterface. Alternatively, the customer may interact with a merchant in aperson to person situation, or via a telephone call center or otherchannel. The customer may use a payment enabler transaction card, whichis issued by a payment enabler such as a credit card issuer. Further,the payment enabler transaction card may be supported by or compatiblewith systems of an interchange entity.

Once the customer initiates the purchase by the customer's interactionwith a merchant, for example, the merchant may submit the purchaseinformation to process the purchase information and effect thetransaction. For example, the submission of the purchase informationmight include the merchant entering information into a cash register orother point of sale or other terminal. Alternatively, the submission maybe performed over the Internet and include the merchant interfacing witha Website, using HTML, XML or other code or protocols, for example. Whenthe merchant transmits the purchase information, in accordance with oneembodiment of the invention, the purchase may be tested forclassification as a microtransaction, for instance by testing if thetotal amount of the purchase price is below a predetermined threshold.Once the purchase has been classified as a microtransaction, regular orother transaction, the purchase information may thereafter be forwardedbased on that classification.

As described above, a merchant may submit purchase information using theInternet. This is one illustrative situation in which a fee might beimposed upon the merchant submitting the information. For example, thefee may be imposed, in some logical manner, based on the data submittedby the merchant. This approach may be characterized as a “pay for byte”approach.

Alternatively, other fee arrangements might be imposed by which analternate interchange entity as described below, for example, mightcollect a small fee for the microtransaction. For example, a customerand/or a merchant effecting a microtransaction might be forwarded to aWebsite maintained by an alternate interchange entity. In order toeffect the microtransaction, the customer and/or merchant may berequired to “click” through various pages on the website, in somelogical manner. This passage through the pages will result in effectingthe desired microtransaction. In addition, a fee may be incurred by thecustomer and/or the merchant as the customer and/or a merchant clicks ona certain page or pages in the website. Accordingly, a fee arrangementmay be used that may be characterized as a “pay for click” arrangement,in accordance with one embodiment of the invention. Other feearrangements may also be utilized by which the alternate interchangeentity, for example, collects a nominal fee for the microtransaction.

As described herein, a “pool” of funds may be used in conjunction withthe microtransaction processing of the invention. The above-described“pay for click” arrangement may result in a debit or a credit, inaccordance with embodiments of the invention. To explain, if aparticular user clicks to access a particular information page in awebsite, for example, that user might pay a five-cent fee for thataccess. Such a five-cent debit may then be deducted from themicrotransaction pool that is associated with that particular user. Thisassociation might be provided in any suitable manner, such as through acommunication between the user's computer and the entity maintaining thepool of funds.

Further, the user's action might result in a credit to the pool, whichis associated with the user. That is, the user might click on anadvertisement in a web page. However, in contrast to the “‘pay forclick” or “pay for byte” arrangement, the user's pool is then creditedfive cents for viewing the advertisement. Any of a wide variety of otherarrangements may be employed in which a funds pool, which is associatedwith a user as discussed in detail below, is debited or credited basedon the actions of the user, i.e., whether the user clicks on aparticular link, for example. In short, the actions of the user resultin continued adjustment of the dollar amount in the funds pool. Asdescribed below, the funds pool is used to effect microtransactions.

As described in detail below, purchase information, which relates to apurchase by a customer, may be forwarded to an interchange entity, to analternate interchange entity, or to both. For example, the purchaseinformation might be forwarded over the Internet. Once the purchaseinformation has been forwarded to the interchange entity or thealternate interchange entity, the purchase information will be processedto effect, i.e., to complete, the microtransaction between the customerand the merchant. The various aspects of the method of the inventionwill be described below.

It should be appreciated that a merchant may use the systems and methodsof the invention to process microtransactions for any of a variety ofreasons. For example, a so called fast-food restaurant may use themethod of the invention to provide customers the convenience of using acredit card. As described herein, the method of the invention, inprocessing microtransactions, provides faster processing for credit cardtransactions as compared with traditional credit card transactions.However, the faster processing may be accompanied by reducedauthorization and/or approval procedures. Accordingly, in accordancewith some embodiments, the invention may be more susceptible tofraudulent transactions than traditional credit card transactions.However, for example, a merchant may deem that the appeal of offeringcustomers the use of credit cards may increase business and throughput.As a result, a merchant may implement the processing ofmicrotransactions, with the knowledge that the increase in fraudulenttransactions will be off-set by the increased business. In short, therisk of losing a hamburger every fifty transactions may be outweighed bythe increased throughput, for example. The systems and methods of theinvention may be used in any of a wide variety of other businessenvironments. Further, any of a variety of circumstantial reasons mayjustify a merchant to use the systems and methods of the invention,i.e., so as to process microtransactions.

In accordance with a further aspect of the invention, the throughput oftransactions may actually trigger the initiation of microtransactionprocessing. That is, for example, during off-peak hours, traditionalcredit card processing may be used by a fast-food merchant. However,once the throughput increases above a certain threshold level, theprocessing systems of the merchant might automatically switch toperforming the microtransactions of the invention. The threshold mightbe based on any of a variety of parameters such as a mathematicalcalculation weighing risk against the benefit of the high throughput,which is afforded by using microtransaction processing.

As should be appreciated, the microtransaction processing of theinvention may be particularly useful in the environment of the Internetand transactions over the Internet. For example, one illustrativescenario might occur when a first user solicits a second user to find anitem of information. The first user might post the request forinformation in a chat room, for example. The second user observes therequest in the chat room and, for a five dollar fee, conducts searchingon the Internet to find and report the item of information to the firstuser. The second user might be characterized as a bounty hunter ofsorts. This low dollar amount transaction, as well as a wide variety ofother transactions, may effectively use the microtransaction processing,in accordance with the various embodiments of the invention. Further,such a transaction might effect an associated “funds pool” of each ofthe first user and the second user, i.e., so as to adjust the balance ineach of the respective user's funds pool, as is described below.

As used herein, a “payment enabler” may be a financial institution, suchas a bank, or any other entity that controls and/or monitors an accountfor a customer. Further, an “interchange entity” as used herein might beVisa or Master Card, for example, or any other entity that serves toprocess transactions that are effected by a customer for an account,wherein such account is controlled and/or monitored by a paymentenabler.

Further, as used herein, a “customer” means any person, device,mechanism or other entity purchasing or leasing an item, any person orentity obtaining services, or any person or entity performing any othertype of transaction, for example. Further, a “merchant” as used herein,means any entity that interacts with the customer in effecting atransaction, such as a purchase or lease of goods, a purchase ofservices, or any other activity or transaction in which a customer mightengage, for example.

As used herein, the term “purchase” means any transaction effected by aperson or an entity, i.e., a customer. Accordingly, a customer making apurchase might be a person or entity purchasing an item, a personobtaining personal services, or an entity performing any other type oftransaction, for example.

Accordingly, a customer might be in the form of a robotic entity thatperiodically downloads software from a software provider, i.e., amerchant. Illustratively, a $2 charge, i.e., a microtransaction, isassociated with each download. The various embodiments of the system andmethod of the invention may be used to effect a recurringmicrotransaction in such a situation.

FIG. 1 is a block diagram showing an exemplary transaction system 1000,which utilizes the method of the invention in accordance with oneembodiment. As shown in FIG. 1, the transaction system 1000 includes acustomer 10, a merchant portion 30 and a payment enabler 40. Themerchant portion 30 is representative of any merchant that interactswith the customer to effect a transaction. Further, the transactionsystem 1000 includes an interchange entity 50 and an alternateinterchange entity 60. These various components of the transactionsystem 1000 perform a variety of activities utilizing the processes ofthe invention, as described herein. The interchange entity 50 may becharacterized as a “traditional interchange entity” in that it processestransactions in a traditional manner charging the typical interchangefee. In contrast, the “alternate interchange entity” 60 processestransactions in accordance with the systems and methods of the inventionas described herein.

As shown in FIG. 1, the customer 10 interacts with the merchant portion30 utilizing a communication interface 32. The communication interface32 may be in the form of a network or over the Internet, for example.Alternatively, it should be appreciated that the communication interface32 may simply be in the form of verbal communication between thecustomer 10 and the merchant portion 30, in conjunction with the use ofa transaction card 12, i.e., a type of transaction account. Inaccordance with the example of FIG. 1, the transaction card 12 is in thepossession of the customer 10 and may be used to effect purchases.

As used herein, a “transaction account” and/or a “payment enablertransaction account” means any account or physical card or other paymentdevice, for example, that is used by a customer that allows thatcustomer to perform any of a wide variety of transactions, which relateto such account or payment vehicle or device. For example, thetransaction account might be in the form of a credit card, debit card,stored value card, smart card, or any other type of card, electronicaccount, or payment device or vehicle, such as a radio frequencyidentification device associated with an account. Further, transactionsperformed utilizing the transaction account include electronicallyaccessing funds, mutual funds, money market accounts, margin accounts,bank accounts, sweeps card accounts, a line of credit, stockinformation, electronically accessing information such as addressinformation, or performing other transactions, for example. Inaccordance with some embodiments of the invention, the invention may usea variety of devices, which the customer carries, so as to initiate themicrotransaction, i.e., such as a plastic credit card type device, aradio frequency identification device as noted above, or other datacarrying device, for example. Such a device might triggermicrotransaction processing, as described herein, directly, i.e., suchthat the transaction is automatically passed on to a microtransactionnetwork.

With further reference to FIG. 1, the merchant portion 30 collects avariety of information from the customer 10, some or all of which maycontained on the transaction card 12, in accordance with one embodimentof the invention, and submits that information for processing.Illustratively, as shown in FIG. 1, the information may be submitted forprocessing utilizing an information packet 16, i.e., a collection ofdata. As described below, the information packet 16 may be transmittedover the Internet 70, for example, to the interchange entity 50 or thealternate interchange entity 60. The Internet 70 may utilize a suitablemedium 72 to support the communications between the various componentsof the transaction system 100, such as a telephone network. It should ofcourse be appreciated that communications between the components of atransaction system 1000 may be performed over other communicationsystems, and is not limited to the Internet.

As described above, a customer 10 possesses and utilizes a transactioncard 12, or similar device, to effect a transaction with the merchantportion 30. FIG. 2 is a diagram showing the transaction card 12 infurther detail, in accordance with one embodiment of the invention.

The transaction card 12 may physically be in the form of a typicalcredit card, for example. As shown in FIG. 2, the transaction card 12includes a magnetic strip 14. The magnetic strip 14 may contain any of awide variety of data. In further explanation of the systems and methodsof the invention, such data contained on the magnetic strip 14 is shownin FIG. 2 as data files 80.

The data files 80 contain a variety of files 81-89. As should beappreciated, the data files 80 contain a data file format informationfile 81. The data file format information file 81 is utilized tomaintain the various files, as is known in the art. Further, the datafiles 80 contain information regarding the particular customerpossessing the transaction card 12, as well as the various entities withwhich that customer interacts in doing business with the transactioncard 12. Accordingly, the data files 80 include payment enablerinformation file 82, and an interchange entity information file 83.Further, in accordance with embodiments of the invention, the data files80 also include an alternate interchange entity information file 84. Thedata files 80, as shown in FIG. 2, further include an account nameinformation file 85, an account number information file 86, as well asan encryption information file 88. Further, the data files 80 include ablank data file 89. The blank data file 89 may be used to contain dataas is desired or necessary.

With respect to the encryption information file 88, it should beappreciated that the systems and methods of the invention may utilizeknown encryption techniques in sending, receiving and storingconfidential data, such as using PKI (Public Key Infrastructures). PKIrefers to systems for managing public and private keys and credentialsused in public key cryptography systems. PKI provides the attributes ofconfidentiality, message integrity, authentication of the identity ofthe key holder, nonrepudiation of the transaction by the key holder, andauthorization, all of which are desired for secure financialtransactions. It should be appreciated that the methods of theinvention, and the various communications utilized in the invention, mayuse PKI, as well as other encryption techniques.

In further reference to FIG. 2, the data files 80 may include amicrotransaction threshold amount file 87, as is described below. Themicrotransaction threshold amount file 87 controls the classification ofa particular transaction as being a microtransaction. As a result, themicrotransaction threshold amount 87 effects the manner in which aparticular transaction is processed, as well as the particular entitythat is performing the processing of the transaction. Further aspects ofthe transaction card 12 will be described below.

FIG. 3 is a diagram showing further details of the information packet16. As described above, a customer 10 interacts with a merchant portion30 utilizing a transaction card 12. This interaction between thecustomer 10 and the merchant portion 30 results in the initiation of atransaction. In order to process the transaction, the merchant portion30 collects various data from the customer 10 and the customer'stransaction card 12, and places that data into an information packet 16.As illustrated in FIG. 1, the information packet 16 is then output fromthe merchant portion 30 to an appropriate recipient. FIG. 3 is a diagramshowing further details of the information packet 16.

As shown in FIG. 3, the information packet 16 includes both static datafiles 80 and dynamic data files 90. The static data files 80 containinformation that will not vary between the various purchases of acustomer. That is, the static data files 80 contain the same informationas the data files 80, which are contained in the transaction card 12,described above.

Further, the information packet 16 includes dynamic data files 90. Thedynamic data files 90 change from one purchase to a next, for example.The dynamic data files 90 include a data file format information file92, which organizes the various information in the dynamic data files90. Further, the dynamic data files 90 include a purchase priceinformation file 94, a merchant information file 96, and a routinginformation file 98.

The purchase price information file 94 contains data regarding thepurchase price for a particular transaction. Further, the merchantinformation file 96 is a data file that contains information regarding aparticular merchant, with which the customer 10 has interacted toinitiate the transaction. Further, the routing information file 98contains information relating to routing of the information packet 16.For example, the routing information 98 may contain informationregarding routing of the information packet 16 to an interchange entity50, an alternate interchange entity 60, or alternatively a paymentenabler 40. For example, the routing information 98 may be provided by acustomer or merchant, may be imbedded on the transaction card 12, or maybe generated based on information from both the transaction card 12 andthe merchant portion 30, for example.

Hereinafter, FIG. 4-FIG. 13 will be described in conjunction with thetransaction system 1000 of FIG. 1. In particular, FIG. 4 is high levelflow chart showing the process in accordance with one embodiment of theinvention. The various steps of the process as set forth in FIG. 4 willbe described in further detail in the flow charts of FIG. 5-FIG. 13.That is, the flow charts of FIG. 5-FIG. 13 describe various embodimentsof the high level process set forth in the flow chart of FIG. 4.

As shown in FIG. 4, the process in accordance with one embodiment of theinvention is initiated in step 100, at which time a transaction isinitiated. After step 100, the process passes to step 200. In step 200,a purchase is initiated by a customer 10 interacting with a merchant 30.As a result of this interaction, purchase information is generated. Thispurchase information may be obtained from each of the transaction card12, the customer 10, and/or the merchant portion 30. After step 200, theprocess passes to step 300. In step 300, the merchant portion 30, i.e. amerchant interacting with the customer, submits the purchase informationfor processing. As described above, this submission may be in the formof transmitting an information packet 16. After step 300, the processpasses to step 400.

In step 400, a determination is made whether the purchase is amicrotransaction. It should be appreciated that this determination maybe performed before the information packet 16 is transmitted by themerchant portion 30. This approach might in particular be used in asituation in which the interchange entity, or the alternate interchangeentity, imposes a fee upon receipt of the information packet. That is,in accordance with this embodiment, the merchant portion 30, utilizingthe transaction card 12, determines whether the particular transactionis a microtransaction. As a result of this determination, theinformation packet 16 is then output to an appropriate recipient, i.e.,the interchange entity, or the alternate interchange entity, forexample. However, it should be appreciated that the determination that atransaction is a microtransaction may be performed at some othersuitable point in the processing. For example, the determination thatthe transaction is a microtransaction might be determined at a suitablealternate interchange entity, in accordance with one embodiment of theinvention. That is, an alternate interchange entity might be disposedbetween the merchant and the normal interchange entity. This alternateinterchange entity would then intercept and process microtransactions,while forwarding on non-microtransactions to the normal interchangeentity for normal processing.

In step 400, the merchant portion 30 may determine that the purchase isnot a microtransaction. As a result, the process passes to step 500. Instep 500, the merchant portion 30 forwards the purchase information tothe interchange entity 50 for traditional processing. That is, since themonetary amount of the purchase price is not low enough to classify thepurchase as a microtransaction, typical processing may take placebetween the merchant, the interchange entity 50 and the payment enabler40. After step 500, as described above, the process passes to step 900.

Alternatively, the merchant portion 30 may determine that the purchaseis indeed a microtransaction. As a result, the process passes to step600. In step 600, the purchase is classified as a microtransaction.Then, the process passes to step 700. In step 700, in accordance withthis embodiment, the merchant portion 30 forwards the purchaseinformation for processing, as a result of the classification of thepurchase as a microtransaction. In accordance with the variousembodiments of the invention, the purchase information might beforwarded to an interchange entity 50, or alternatively, may beforwarded to an alternate interchange entity. After step 700, theprocess passes to step 800.

In step 800, the entity receiving the purchase information, i.e. whetherit be the interchange entity 50 or alternate interchange entity 60,processes the purchase information to effect the microtransactionbetween the customer and the merchant. After step 800, the processpasses to step 900 as shown in FIG. 4. In step 900, the transaction isterminated.

FIG. 5 is a flow chart showing the features of FIG. 4 in further detail.Specifically, FIG. 5 shows the step of “is the purchase amicrotransaction?” step 400 of FIG. 4 in further detail.

As shown in FIG. 5, the process starts in step 400. After step 400, theprocess passes to step 402. In step 402, the merchant portion 30retrieves the purchase price, i.e., the amount of the transaction, fromthe purchase information. Then, in step 404, the merchant portion 30retrieves a microtransaction threshold amount 404. For example, thisinformation might be obtained from the microtransaction threshold amountfile 87 in the transaction card 12.

After step 404, the process passes to step 406. In step 406, themerchant portion 30 determines whether the microtransaction thresholdamount is greater than or equal to the purchase price. If yes, then theprocess passes from step 406 to step 420 in which the purchase isdetermined to be a microtransaction. After step 420, as shown in FIG. 5,the process passes to step 422. In step 422, the process advances tostep 600, as shown in FIG. 4.

Alternatively, the transaction may not be a microtransaction.Accordingly, the process passes from step 406 to step 410 in which thepurchase is determined to not be a microtransaction. After step 410, theprocess passes to step 412. In step 412, the process passes to step 500,as shown in FIG. 4.

FIG. 6 is a flowchart showing in further detail the “process thepurchase information to effect the microtransaction between the customerand the merchant.” step 800 of FIG. 4, in accordance with one embodimentof the invention. In accordance with this embodiment, the purchaseinformation has been forwarded directly to an alternate interchangeentity 60. As described above, this routing may be controlled by therouting information 98 in the information packet 16. Further, themerchant or customer might dictate the particular routing, i.e., so asto select a particular embodiment of the invention that is chosen andimplemented. This might be performed by the customer entering a suitablecode when initiating the transaction for example, or alternatively, insome other suitable manner.

Once the purchase information is received by the alternate interchangeentity, initial processing of the purchase information is performed, asillustrated in step 810 of FIG. 6. After step 810, the process passes tostep 815. In step 815, the alternate interchange entity generatesprocessed purchase information. That is, the purchase information may beprocessed in a suitable manner as is desired or necessary by thealternate interchange entity. This processed purchase information isthen forwarded to a payment enabler. Accordingly, the flowchart of FIG.6 illustrates a situation, in accordance with one embodiment of theinvention, in which the alternate interchange entity interacts directlywith the payment enabler.

Accordingly, in step 820 of FIG. 6, the alternate interchange entityinteracts with the payment enabler 40 to obtain authorizationinformation for the particular transaction requested by the customer 10.After step 820, the process passes to step 830 as shown in FIG. 6. Instep 830, the alternate interchange entity, which has previouslyobtained “authorization information” from the payment enabler 40,outputs this authorization information to the merchant portion 30.

Further details of each of step 820 and step 830 are described below.After step 830, the process passes to step 839. In step 839, the processreturns to step 900, as shown in FIG. 4.

FIG. 7 is a flowchart showing in further detail the “alternateinterchange entity interacts with payment enabler to obtainauthorization information” step of FIG. 6. After the subprocess startsin step 820, the process passes to step 821 as shown in FIG. 7. Step 821illustrates that the alternate interchange entity outputs processedpurchase information to the payment enabler to request authorization forthe microtransaction. Then, the process passes to step 822. In step 822,the alternate interchange entity 60 performs a determination whether aresponse is received from the payment enabler.

That is, it should be appreciated that the alternate interchange entity60 may not possess as established a network or communicationcapabilities as the interchange entity 50. Accordingly, it may be morelikely that an alternate interchange entity 60 may not be able tocommunicate with the payment enabler 40, than if the transaction wasprocessed directly through the interchange entity 50. However, this maybe characterized as a “trade-off” of sorts since interchange fees areavoided for the microtransaction, i.e., as a result of being processedby the alternate interchange entity 60.

In further explanation of this aspect of the invention, FIG. 7illustrates that a response may not be obtained from the paymentenabler. As a result, the process passes to step 823 as shown in FIG. 7.In step 823, the process determines that the communication from thealternate interchange entity to the payment enabler failed. Then, theprocess passes to step 824 in which a wait period is initiated. Itshould be appreciated that this wait period may very substantially basedon the particular circumstances of the transaction being effectedbetween the merchant and the customer.

After step 824, the process passes to step 825 in which a determinationis made whether all the wait periods have been used. If yes, then instep 825′ the alternate interchange entity generates an indication,which may be contained in the authorization information, that thepayment enabler did not receive the processed information and that themicrotransaction cannot be processed at this time. Then, the processpasses to step 839. In step 839, the process returns to step 830, asshown in FIG. 6.

Alternatively, the process may determine in step 825 that all the waitperiods have not been used. As a result, the process passes from step825 back to step 821. Thereafter, the processing proceeds as describedabove.

In accordance with a further aspect of the invention, it should beappreciated that the merchant portion 30 may not be able to communicatewith the alternate interchange entity 60, i.e., rather than thealternate interchange entity 60 not being able to communicate with thepayment enabler 40. Accordingly, the alternate interchange entityinformation file 84, for example, might contain an appropriate notice inthis situation. For example, such a notice might be conveyed to thecustomer 10, through the merchant 30, that this particular transactionis a microtransaction, and further, that the alternate interchangeentity could not be contacted to process this microtransaction.Thereafter, the customer might be given the option to proceed with thetransaction utilizing the interchange entity 50 in the typical manner,and, as a result, incur the typical interchange fee. However, it shouldof course be appreciated that in this situation, the interchange feemight exceed the actual purchase amount of the microtransaction.

In further explanation of FIG. 7, the alternate interchange entity maybe successful in communicating with the payment enabler. As a result,the process passes from step 822 to step 826. In step 826, the alternateinterchange entity, based on information received from the paymentenabler 40, performs a determination whether the microtransaction isauthorized. The authorization may be determined in any suitable manner.If no, i.e., the microtransaction is not authorized, then the processpasses from step 826 to step 827. In step 827, the alternate interchangeentity 60 provides an indication in the generation of authorizationinformation, which will be forwarded to the merchant portion 30, of thenon-approval. After step 827, the process passes to step 839. In step839, the process returns to step 830, as shown in FIG. 6.

Alternatively, authorization may be obtained for the microtransaction.As a result, the process passes from step 826 to step 828. In step 828,the alternate interchange entity 60 provides an indication, in theauthorization information, of approval. Then, the process passes to step829.

In step 829, the alternate interchange entity may place a furthersuitable notice in the authorization information. For example, such anotice may contain information indicating that the terms of theagreement between the customer and the interchange entity will not applyto the transaction, i.e., since the interchange entity is not handlingthe transaction. Alternatively, or in addition to, the customer noticemay further include an indication that the terms of agreement betweenthe customer and the alternate interchange entity will be applied to themicrotransaction. The terms of such agreement may have previously beenagreed upon by the customer 10, the payment enabler 40, and/or thealternate interchange entity 60, as well as the interchange entity 50.After step 829, the process passes to step 839. In step 839, the processreturns to step 830, as shown in FIG. 6.

As described above with reference to step 820 of FIG. 6, the alternateinterchange entity interacts with the payment enabler to obtainauthorization information. A particular embodiment of the process step820 is described above in conjunction with FIG. 7. However, the systemand method of the invention are not limited to the process of FIG. 7.That is, various other techniques may be used relating to authorizationof a microtransaction requested by a person dealing with a merchant.

To further explain in accordance with one aspect of the invention, itshould be appreciated that the fee, i.e., the interchange fee forexample, associated with effecting a microtransaction may be relativelysmall. As a result, it may be desirable to reduce the processingassociated with the microtransaction. One manner in which to reduce theprocessing is to reduce the authorization related processing. Forexample, the method of the invention in effecting a microtransactionmight utilize traditional authorization techniques, or alternatively,might not utilize any authorization. In general, it should beappreciated that authorization of a microtransaction is inversely tiedto risk, i.e., of non-payment, associated with the microtransaction.That is, as authorization requirements are decreased, the riskassociated with the microtransaction increases. Further, increased riskin the microtransaction results in a question of who should bear theincreased risk, i.e., the merchant, alternate interchange entity or thepayment enabler, for example.

In accordance with one embodiment, the method of the invention onlyrequires authorization once a problem is detected with a particularcustomer's account. That is, for example, so long as the customer'smonthly payment is received within some time frame, as desired, thatcustomer is allowed to effect a microtransaction without authorization.However, if the customer's monthly payment is not received within sometime frame resulting in a “problem account,” then authorization will berequired for a microtransaction. This technique of the invention mightbe implemented by providing merchants with information relating to whichaccounts require authorization, in conjunction with utilizing a “noauthorization needed” default. That is, if no information is received bya merchant for a particular account, i.e., a problem account, then themerchant assumes that no authorization is required to process amicrotransaction for the account.

As a further alternative in accordance with one embodiment of theinvention, the method of the invention does not allow a microtransactiononce a problem is detected with a particular customer's account. Thatis, so long as the customer's monthly payment, for example, is receivedwithin some time frame, as desired, that customer is allowed to effect amicrotransaction. However, if the customer's monthly payment is notreceived within some time frame resulting in a problem account, then amicrotransaction is not allowed by the merchant. Rather, the customer isthen required to utilize traditional techniques for effecting thedesired transaction. This technique of the invention is also implementedby providing merchants with information relating to which accounts areproblem accounts.

The above techniques of course require that merchants be informed of anyproblem accounts. Illustratively, in accordance with one embodiment ofthe invention, merchants who wish to participate in processingmicrotransactions might contact the payment enabler to sign up, at acost, for what might be characterized as a “microtransaction service.”

The payment enabler will provide updated information regarding problemaccounts for all merchants who participate in the microtransactionservice. This updated information might be provided utilizing theInternet. In utilizing this arrangement, the merchant who participatesin the microtransaction service may limit its risk. In accordance withone embodiment of the invention, the merchant might contact the paymentenabler after a predetermined period of time has passed, using asuitable website arrangement, for example. In response, the paymentenabler provides updated information to the merchant regarding problemaccounts, in conjunction with charging the merchant a fee. This feemight be imposed upon the merchant accessing and using the website, orin some other manner.

So long as the merchant contacts the payment enabler after apredetermined period of time has passed, the payment enabler agrees toassume the risk of non-payment of the microtransaction. However, if themerchant does not contact the payment enabler after a predeterminedperiod of time has passed, the merchant, rather than the paymentenabler, will assume the risk of non-payment of the microtransaction.Once the merchant again contacts the payment enabler for updatedinformation, i.e., such that the merchant has current data on “problemaccounts” serviced by the payment enabler, the risk will again pass tothe payment enabler.

Alternatively, a merchant may decide to process microtransactions, butnot participate in the service at all. Accordingly, the merchant willnot be informed of problem accounts. If the merchant does notparticipate in the service, the merchant assumes the risk of non-paymentof the microtransaction, in accordance with one embodiment of theinvention.

In further explanation of the method of the invention and theflowcharts, FIG. 8 is a flowchart showing in further detail the“alternate interchange entity outputs authorization information tomerchant” step 830 of FIG. 6. That is, in step 830, the authorizationinformation has been obtained through the processing of step 820. Thisauthorization information may then be communicated to the merchant.Accordingly, after step 830, the process passes to step 832. In step832, the alternate interchange entity sends authorization information tothe merchant. Then, in step 834, the authorization information isreceived by the merchant. After step 834, the process passes to step835. In step 835, the merchant conveys the authorization information tothe customer. The authorization information may contain a variety ofinformation, as is described above.

After step 835, the process passes to step 836. In step 836, themerchant obtains acknowledgement from the customer of receipt of theauthorization information. That is, this acknowledgment of receipt fromthe customer may be deemed necessary to complete the requestedmicrotransaction. In particular, it should be appreciated that theacknowledgement might be desired in the situation where the typicalterms, i.e., between the customer and the interchange entity, will notapply since the alternate interchange entity is processing thetransaction. After step 836, the process passes to step 838. In step838, the process returns to step 839, as shown in FIG. 6.

As described above, in step 835 of FIG. 8, the merchant conveys theauthorization information to the customer. This is one example of howthe customer “sees” the transaction. Any of a variety of othertechniques may be utilized to provide the customer with informationregarding performed microtransactions, as is desired. This informationmay pertain to a particular microtransaction or an aggregate ofmicrotransactions. For example, the customer might be mailed a monthlysummary bill. Alternatively, the customer might be sent an e-mail eachtime a microtransaction is performed, in conjunction with a periodicsummary bill. Alternatively, the customer might be given access to awebsite upon which that customer's microtransaction activity isdocumented. It should be appreciated that any security precautions maybe taken in conjunction with such a website, as is desired.

FIG. 9 is a flow chart showing a different embodiment of the process ofFIG. 4. Specifically, the flowchart of FIG. 9 illustrates a furtherembodiment of the “process the purchase information to effect themicrotransaction between a customer and the merchant”, which isdifferent from the embodiment set forth in FIG. 6. In particular, theembodiment of the method of the invention as illustrated in FIG. 9includes the alternate interchange entity 60 interacting with theinterchange entity 50, as described below.

As shown in FIG. 9, the process starts in step 800′. After step 800′,the process passes to step 840. In step 840, the alternate interchangeentity aggregates the microtransaction with other microtransactions toform an aggregated transaction. Further details of step 840, inaccordance with two illustrated embodiments, will be described belowwith reference to FIG. 10 and FIG. 12.

After step 840, the process passes to step 890. In step 890, thealternate interchange entity outputs the aggregated transaction to theinterchange entity. Then, the process passes to step 892 in which theinterchange entity processes the aggregated transaction as a singletransaction, utilizing the typical interchange fee. After step 892, theprocess passes to step 894. In step 894, the process returns to step900, as shown in FIG. 4.

As referenced above, FIG. 10 is a flowchart showing in further detailthe “alternate interchange entity aggregates the microtransaction withother microtransactions to form an aggregated transaction.” As shown inFIG. 10, the subprocess starts in step 840. Then, the process passes tostep 851.

In step 851, the alternate interchange entity adds the microtransaction,which was effected between the customer 10 and the merchant portion 30,to a pool of microtransactions. This pool of microtransactions maycontain other customers' microtransactions, or alternatively, maycontain other microtransactions effected by that particular customer.After step 851, the process passes to step 852. In step 852, thealternate interchange entity adds the total monetary value of the poolof microtransactions.

That is, the alternate interchange entity totals all themicrotransactions currently in the pool. For example, 20 transactionseach at a dollar amount of $2.00 would result in a total of $40. Then,the process passes to step 853. In step 853, the alternate interchangeentity performs a determination whether the total value, as determinedin step 852, is greater than or equal to a predetermined amount. Thispredetermined amount may be determined by the alternate interchangeentity based on any of a variety of factors.

The total value of the pool, which has been attained, might not, at thistime, exceed the predetermined amount. As a result, the process passesfrom step 853 to step 854. In step 854, the process waits for furtheradditions to the pool of microtransactions. Further, as illustrated inthe subsequent step 855, additional microtransactions may be receivedand, as a result, added to the pool of microtransactions. Then, theprocess returns to step 852. In step 852, the alternate interchangeentity 60 may again add the total monetary amount of the pool ofmicrotransactions. As a result, the comparison of step 853 may result ina determination that the total value of the microtransactions in thepool does indeed exceed the predetermined amount. This triggers thealternate interchange entity 60 to perform further processing.

Specifically, the process passes from step 853 to step 856. In step 856,the pool of microtransactions is complete and the total value of thatpool is saved into a suitable memory. Thereafter, further processing isperformed on the completed pool, as shown in step 857. Further detailsof step 857 are described below with reference to FIG. 11. After step857, the process passes to step 858 as shown in FIG. 10. In step 858,the process returns to step 890 of FIG. 9.

As referenced above, FIG. 11 is a flow chart showing in further detailthe “perform further processing on the completed pool” step 857 of FIG.10. As shown in FIG. 11, the process passes from step 857 to step 860.

In step 860, the alternate interchange entity 60, in accordance with oneembodiment of the invention, generates an aggregated transaction thatincludes each microtransaction in the completed pool, which wasgenerated as described above. Then, the process passes to step 862. Instep 862, the alternate interchange entity assigns the aggregatedtransaction to an interim account. This interim account is controlled bythe alternate interchange entity and, in accordance with this embodimentof the invention, was previously set up by the alternate interchangeentity.

As described below, this aggregated transaction will be forwarded fromthe alternate interchange entity to the interchange entity forprocessing as a single transaction. Accordingly, the interchange feesare substantially reduced for each microtransaction in the pool formingthe aggregated transaction. It should be appreciated that this reducedinterchange fee may indeed be applied to each microtransaction in somesuitable manner. For example, the interchange fee associated with thesingle transaction, processed by the interchange entity 50, may beproportionately distributed between the microtransactions in the poolbased on the dollar amount of each microtransaction. Alternatively,other suitable techniques or methodologies might be utilized to allocateand distribute the single interchange fee that is due to the interchangeentity 50. For example, the single interchange fee might be distributedbased on riskiness of the transaction and/or based on an arrangementwith a merchant possibly involving volume discounts, for example.Further, for example, the allocation of an interchange fee might bereduced for a particular customer based on activities of the customer.

For example, the allocation of an interchange fee might be reduced basedon the particular customer clicking and viewing an advertisement on theweb, for example. Alternatively, the allocation of an interchange feemight be allocated based on the activities of a merchant. For example,the allocation might be based on the volume of sales observed by amerchant on a particular day, since at the end of the day the merchantwill process all the sales for that day as an aggregated transaction, inaccordance with one embodiment of the invention. As the volume of salesincreases, the cost to each customer decreases.

After step 862, the process passes to step 864. In step 864, thealternate interchange entity 60 forms an aggregated transaction datafile containing customer aggregate information. The customer aggregateinformation includes information relating to customers performing theaggregated transaction. This information might include, for example,names, account numbers, or dollar amounts, for example.

In accordance with one embodiment of the invention, the aggregatedtransaction will be forwarded through the interchange entity as a singletransaction and subsequently forwarded to the payment enabler. As aresult, the payment enabler must be able to determine the particularcustomers, and their associated microtransactions, that make up theaggregated transaction. The aggregated transaction data file providesthe information by which the payment enabler 40 may perform thisallocation. Further details of this process are described below.

In further explanation of FIG. 11, once the customer aggregateinformation is assembled in a data file, the process passes to step 865.In step 865, the alternate interchange entity makes a determinationwhether the customer aggregate information is to be or not to beattached to the aggregated transaction, i.e., the aggregated transactionthat will be forwarded to and processed by the interchange entity 50.The decision of step 865 may be determined based on an establishedprotocol or various parameters, as is desired.

Illustratively, the protocol may dictate that the customer aggregateinformation is not to be attached to the aggregated transaction. As aresult, the process passes from step 865 to step 867. In step 867, thealternate interchange entity 60 assigns a matching code to each of theaggregated transaction, which will be forwarded through the interchangeentity, and to the customer aggregate information, which will beforwarded directly to the payment enabler 40. This matching codeinformation will be utilized by the payment enabler 40 for a latermatching. This will allow the payment enabler 40 to determine theparticular microtransactions that make up an aggregated transaction.After step 867, the process passes to step 868. In step 868, thealternate interchange entity forwards the customer aggregate informationto the payment enabler 40. Then, the process passes to step 869.

Alternatively, in step 865, the process may determine that the customeraggregate information is indeed to be attached to the aggregatedtransaction. As a result, the process passes from step 865 to step 866.In step 866, the alternate interchange entity performs an attachment ofthe customer aggregate information to the aggregated transaction foroutputting to the interchange entity. For example, the customeraggregate information may be contained in a suitable data file which isattached to the aggregated transaction information. After step 866, theprocess passes to step 869.

Accordingly, subsequent to either of step 868 or step 866, the processpasses to step 869. In step 869, the process returns to step 858, asshown in FIG. 10.

FIG. 12 is a flow chart showing in further detail the “Alternateinterchange entity aggregates the microtransactions with othermicrotransactions to form an aggregated transaction” step 840 of FIG. 9in accordance with a further embodiment of the invention. In summary,the process of FIG. 12 illustrates an embodiment of the invention inwhich a predetermined aggregate amount is generated and submitted to theinterchange entity upon an initial microtransaction being requested bythe customer.

As shown in FIG. 12, the process starts in step 840′ and passes to step872. In step 872, the alternate interchange entity receives a firstmicrotransaction request by the customer. Illustratively, the monetaryamount of this microtransaction may be $5.00, for example. After step872, the process passes to step 874.

In step 874, the alternate interchange entity outputs a notice to thecustomer, through the merchant, that the microtransaction will not beafforded non-microtransaction benefits. Further, to ensure that thecustomer is aware of this aspect of the microtransaction beingprocessed, the alternate interchange entity waits for acknowledgementfrom the customer. This acknowledgement may be provided through themerchant to the alternate interchange entity in any suitable manner.

After step 874, the processes passes to step 875. In step 875, thealternate interchange entity generates and outputs a predeterminedaggregate amount to the interchange entity for processing. For example,this amount may be in the monetary amount of $200. It should beappreciated that the typical interchange fee will be applied to whatappears to the interchange entity as a single transaction of $200. Afterstep 875, the process passes to step 876.

In step 876, the alternate interchange entity sets up a temporary fundsaccount for the customer. This temporary funds account possesses abalance. As might be expected, the balance is the difference between thepredetermined aggregate amount, i.e., that was submitted to theinterchange entity, and the first microtransaction amount. Accordingly,in the example above, the initial balance of the temporary funds accountwould be $200 minus $5 equals $195 a balance.

After step 876, the process passes to step 878. In step 878, thecustomer effects further microtransactions. These furthermicrotransactions requested by the same customer are deducted from thebalance of $195. It should be appreciated that no interaction with theinterchange entity 50 occurs with these further microtransactions. Thatis, the customer merely interacts with the alternate interchange entity60 to progressively work down the balance of a temporary funds accountmaintained by the alternate interchange entity. After step 878, theprocess passes to step 879. In step 879, the process returns to step 890of FIG. 9.

In accordance with a further aspect of the invention, the alternateinterchange entity may also perform a role of authentication of aprevious purchase of goods or services, for example, that were effectedvia a microtransaction. For example, a consumer products reportingentity might charge a three-dollar fee to view product reports eachthree months, i.e., a microtransaction. Accordingly, an alternateinterchange entity might initially process the three-dollarmicrotransaction, in accordance with one of the embodiments describedherein for example, and then maintain a repository or database ofmicrotransactions. Further, at some later time after processing themicrotransaction, the alternate interchange entity may then be contactedto authenticate the transaction. Accordingly, the alternate interchangeentity functions as a authentication facility.

FIG. 13 is a flow chart showing in further detail, the “Process thepurchase information to effect the microtransaction between the customerand the merchant” step of FIG. 4, in accordance with a yet furtherembodiment of the invention. That is, FIG. 13 illustrates a variation tothe embodiments shown in FIG. 6 and FIG. 9.

Further, the process illustrated in FIG. 13 illustrates a situationwhere the interchange entity utilizes different protocols formicrotransactions and non-microtransactions, respectively. That is, themicrotransactions receive less benefits, for example, thannon-microtransactions. One example of less benefits might be that thecustomer has a limited ability to argue a transaction. As a result, theinterchange entity charges a lower interchange fee thus making themicrotransactions cost effective for both the interchange entity and thecustomer. Further, the embodiment illustrated in FIG. 13 illustrates asituation in which the customer and the merchant interact directly withthe interchange entity 50.

As shown in FIG. 13, the process starts in step 800″. After step 800″,the process passes to step 882. In step 882, the interchange entity 50receives the microtransaction, which was transmitted from the merchantportion, and initiates processing. After step 882, the process passes tostep 884.

In step 884, the interchange entity retrieves both of thenon-microtransaction protocol, as well as the microtransaction protocol.Further, each of these protocols have respective dollar ranges, forexample as might be the case in the United States, associated with them.For example, the microtransaction protocol may have a monetary range of$0 to $20, for example. After step 884, the processes passes to step886.

In step 886, the interchange entity 50 determines, in accordance withthis illustrative example, that the microtransaction indeed qualifiesfor processing as a microtransaction. Then, in step 887, the interchangeentity outputs an appropriate notice to the customer. For example, thisnotice might be transmitted through the merchant.

Specifically, the notice provides information to the customer indicatingthat the microtransaction protocol will apply and that such protocolwill provide reduced benefits to the customer for the microtransaction.Thereafter, in accordance with the embodiment shown in FIG. 13, theinterchange entity 50 waits for acknowledgement from the customer. Afterstep 887, the process passes to step 888. In step 888, the processreturns to step 900 of the FIG. 4. As described above, in step 900, thetransaction is completed. Accordingly, the systems and methods of theinvention provide effective and efficient techniques to process amicrotransaction.

In accordance with one embodiment of the invention, it should beappreciated that the time of day may affect what is and is not amicrotransaction, i.e., what is the dollar threshold. For example, afast-food restaurant may use the microtransaction processing of theinvention during only peak hours, such as from 11 am to 2 pm. It isduring these hours that the restaurant may deem that the speed andconvenience of the microtransaction processing, over traditional creditcard processing, is justifiable, i.e., as weighed against the increasedrisk of fraudulent transactions. Accordingly, the processing system ofthe merchant might process all transactions which (1) occur between 11am to 2 pm, and (2) involve less than five dollars, asmicrotransactions. However, at other times, no transactions areprocessed using the microtransaction processing of the invention.Alternatively, at other times, only transactions that are less thanthree dollars might be processed as microtransactions. Any of a widevariety of arrangements are possible depending on the particularbusiness needs of a merchant.

In general, it should be appreciated that the microtransactionprocessing in accordance with some embodiments of the invention, may bemore susceptible to fraud then traditional credit card transactions.However, the increased throughput, for example, provided by themicrotransaction processing may outweigh the risk of increased losses.Nevertheless, it may be desired to implement further securityprecautions not present in traditional credit card processing, asdesired. For example, the dollar amount of a user's pool of funds may bemonitored. As a result, abnormal increases in the balance of a fundsaccount may be detected and closely monitored for possible fraud.

As shown in FIG. 1, the alternate interchange entity is separate fromthe merchant portion and other processing components. However, inaccordance with further embodiments of the invention, the alternateinterchange entity may be combined with another component of FIG. 1. Forexample, the alternate interchange entity 60 might be combined with themerchant portion 30, i.e., so as to function as one processing portion.

In explanation of further aspects of the invention, the customerinteracts with a merchant, such as described above and shown in FIG. 1,so as to initiate a microtransaction. In accordance with one embodimentof the invention, the interaction between the customer 10 and themerchant portion 30 may be performed using a radio frequency device,radio frequency identification device, or some other signal transmissiondevice. Such a device might trigger microtransaction processing, asdescribed herein, directly. Illustratively, the radio frequency deviceoutputs a signal to a suitable receiving device at the merchant portion.To explain, the radio frequency device may be physically carried by thecustomer, such as in the customer's watch, in the customer's key chain,for example, or in some other device carried by the customer. Thecustomer might then initiate a purchase at a merchant's store. Uponprompting by the merchant, the customer effects the transmission ofinformation from the radio frequency device, controlled by the customer,to a suitable merchant receiving device, i.e., such as a deviceconnected to the merchant's cash register, for example. The customermight push a button on the radio frequency device, for example. Thereceipt of the information by the merchant receiving device, from thecustomer's radio frequency device, initiates the microtransaction. Sucha radio frequency device might be particularly useful in a toll boothsituation or a fast food restaurant situation, for example.

In accordance with one embodiment of the invention, the customer's radiofrequency device might be dedicated only to microtransactions.Accordingly, upon receipt of the information from the customer's radiofrequency device, the merchant receiving device would immediatelyidentify the transaction as a microtransaction. Further, the transactioninformation might then be automatically forwarded to a microtransactionnetwork. The radio frequency device described above, might be used inconjunction with any of the other features described herein. Further, itshould be appreciated that other devices, as described herein, might bededicated exclusively for microtransactions. Accordingly, the use ofsuch a device itself, by a customer, would trigger the use of amicrotransaction network. Thus, such an exclusive device might not beused for larger dollar amount non-microtransactions.

As described above, FIGS. 1-3 show one embodiment of the system of theinvention. Further, FIGS. 4-13 show various steps of one embodiment ofthe method of the invention. The system of the invention or portions ofthe system of the invention may be in the form of a “processingmachine,” such as a general purpose computer, for example. As usedherein, the term “processing machine” is to be understood to include atleast one processor that uses at least one memory. The at least onememory stores a set of instructions. The instructions may be eitherpermanently or temporarily stored in the memory or memories of theprocessing machine. The processor executes the instructions that arestored in the memory or memories in order to process data. The set ofinstructions may include various instructions that perform a particulartask or tasks, such as those tasks described above in the flowcharts.Such a set of instructions for performing a particular task may becharacterized as a program, software program, or simply software.

As noted above, the processing machine executes the instructions thatare stored in the memory or memories to process data. This processing ofdata may be in response to commands by a user or users of the processingmachine, in response to previous processing, in response to a request byanother processing machine and/or any other input, for example.

As noted above, the processing machine used to implement the inventionmay be a general purpose computer. However, the processing machinedescribed above may also utilize any of a wide variety of othertechnologies including a special purpose computer, a computer systemincluding a microcomputer, mini-computer or mainframe for example, aprogrammed microprocessor, a micro-controller, a peripheral integratedcircuit element, a CSIC (Customer Specific Integrated Circuit) or ASIC(Application Specific Integrated Circuit) or other integrated circuit, alogic circuit, a digital signal processor, a programmable logic devicesuch as a FPGA, PLD, PLA or PAL, or any other device or arrangement ofdevices that is capable of implementing the steps of the process of theinvention.

It is appreciated that in order to practice the method of the inventionas described above, it is not necessary that the processors and/or thememories of the processing machine be physically located in the samegeographical place. That is, each of the processors and the memoriesused in the invention may be located in geographically distinctlocations and connected so as to communicate in any suitable manner.Additionally, it is appreciated that each of the processor and/or thememory may be composed of different physical pieces of equipment.Accordingly, it is not necessary that the processor be one single pieceof equipment in one location and that the memory be another single pieceof equipment in another location.
